ABSTRACT
Background: Aggression, a common symptom of Alzheimer's disease (AD), can impose a significant burden on caregivers, necessitating early institutionalization. Objective: The current study examined the neural basis of aggression and its expression mechanism, to advance the development of effective treatment strategies for aggression in patients with AD. Methods: The study sample included 257 patients; 180 were diagnosed with AD and 77 with amnestic mild cognitive impairment (aMCI). Factor analysis of the neuropsychiatric inventory (NPI) aggression scores was performed, and the correlation between each factor and cerebral blood flow (CBF) was examined via diagnosis of AD or aMCI using statistical parametric mapping. Results: Refusal of care was correlated with reduced CBF in the right hippocampus of patients with AD while no specific related regions could be identified in patients with aMCI. Violent behavior was associated with decreased CBF in the right temporal pole and medial frontal lobe of patients with AD and aMCI. Conclusions: These findings suggest that aggression, measured using NPI includes two distinct symptoms, refusal of care and violent behavior, having different underlying neural bases.

OBJECTIVE: 40-60% of persons living with dementia (PLWD) experience agitation and/or aggression symptoms. There is a need to understand the best method to detect agitation and/or aggression in PLWD. We aimed to identify agitation and/or aggression tools that are validated against a reference standard within the context of PLWD. METHODS: Our study was registered on PROSPERO (CRD42020156708). We searched MEDLINE, Embase, and PsycINFO up to April 22, 2024. There were no language or date restrictions. Studies were included if they used any tools or questionnaires for detecting either agitation or aggression compared to a reference standard among PLWD, or any studies that compared two or more agitation and/or aggression tools in the population. All screening and data extraction were done in duplicates. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Data extraction was completed in duplicates by two independent authors. We extracted demographic information, prevalence of agitation and/or aggression, and diagnostic accuracy measures. We also reported studies comparing the correlation between two or more agitation and/or aggression tools. RESULTS: 6961 articles were screened across databases. Six articles reporting diagnostic accuracy measures compared to a reference standard and 30 articles reporting correlation measurements between tools were included. The agitation domain of the Spanish NPI demonstrated the highest sensitivity (100%) against the agitation subsection of the Spanish CAMDEX. Single-study evidence was found for the diagnostic accuracy of commonly used agitation scales (BEHAVE-AD, NPI and CMAI). CONCLUSIONS: The agitation domain of the Spanish NPI, the NBRS, and the PAS demonstrated high sensitivities, and may be reasonable for clinical implementation. However, a limitation to this finding is that despite an extensive search, few studies with diagnostic accuracy measurements were identified. Ultimately, more research is needed to understand the diagnostic accuracy of agitation and/or aggression detection tools among PLWD.

BACKGROUND: The Cohen-Mansfield Agitation Inventory-Short Form (CMAI-SF) is a 14-item scale for assessing agitation and aggression, derived from the original 29-item CMAI, and completed by a proxy. Because the CMAI-SF has not yet been validated in German language, the aim of this study is to explore its construct validity. METHODS: Baseline data from a cluster-randomized trial to evaluate a non-pharmacological complex intervention for people living with dementia (PlwD) and mild cognitive impairment (MCI) were analyzed. The study sample consisted of 97 shared-housing arrangements (SHAs) in Germany, comprising N = 341 residents with mild to severe dementia and MCI. Trained nursing staff collected data by proxy-rating the CMAI-SF, Neuropsychiatric Inventory-Nursing Home Version (NPI-NH), and QUALIDEM. They also conducted the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). RESULTS: In an exploratory factor analysis, three factors emerged: "aggressive behavior", "verbally agitated behavior", and "physically non-aggressive behavior". The CMAI-SF total score showed good internal consistency (α = .85), and the factors themselves showed adequate internal consistency (α = .75/.76/.73). The CMAI-SF showed convergent validity with the NPI-NH agitation item (r = .66) and the NPI-NH "agitation & restless behavior" factor (r = .82). Discriminant validity was confirmed by a low (r = .28) correlation with the NPI-NH apathy item. Quality of life decreased significantly with agitation, as the CMAI-SF showed a moderate negative correlation with the QUALIDEM total score (r = -.35). CONCLUSIONS: The 14-item CMAI-SF is a time-efficient, reliable, and valid assessment instrument. Three factors emerged that were similar to those already found in nursing home samples for the original CMAI and the CMAI-SF and in day care samples for the CMAI-SF. The findings provide preliminary evidence that the CMAI-SF can be used instead of the CMAI to reduce time, costs, and burden in future trials. TRIAL REGISTRATION: The DemWG study from which data were used to draft this manuscript was prospectively registered on 16 July 2019 at ISRCTN registry (ISRCTN89825211).

The behavioral and psychological symptoms of dementia (BPSD) are experienced by up to 90% of patients with dementia throughout dementia. This study aims to investigate the effect of aromatherapy on agitation in patients with dementia in the community. This prospective cohort study was conducted at a single day-care center for patients with dementia located in northern Taiwan with 2-week and 4-week follow-ups, comparing the severity of agitation between 3 measure points as the primary outcome. The aromatherapy was performed over 5 consecutive days for 4 weeks. Throughout the four-week observation were analyzed by GEE. Significant differences were found in the Chinese version of Cohen-Mansfield Agitation Inventory (CCMAI) total agitation score (ß=-3.622, p=0.037) and physically non-aggressive behavior subscale (ß=-4.005, p=0.004) between aromatherapy group and control group. The severity of dementia-related agitation, especially the severity of physically non-aggressive behavior in demented patients, could be significantly reduced by a four-week intervention of aromatherapy.

Objective: NICE guidelines recommend non-pharmacological interventions as the first-line approach for the management of behaviours that challenge. Recent work, however, highlights dissatisfaction with the lack of detailed guidance in the national guidelines regarding non-drug interventions. This study examines the views of practitioners regarding non-pharmacological treatments. It further explores perspectives on non-pharmacological strategies used in the management of agitation occurring within episodes of behaviours that challenge. Methods: Forty-two experienced practitioners attended a workshop where behaviours that challenge were described as occurring in three phases of agitation, using a framework adapted from the Positive Behaviour Support framework (pre-agitation, triggering and escalating, high level). The participants were asked to populate a template derived from the adapted framework. The completed templates recorded the clinical strategies the participants found useful to (i) prevent the occurrence of agitation, (ii) de-escalate distress and (iii) deal with perceived high levels of agitation. Results: The Positive Behaviour Support conceptual framework was perceived by participants as helpful in organising their clinical work. A number of interventions were suggested as preventative strategies: music therapy, doll therapy, physical activity and generic person-centred communication skills to enhance wellbeing. In contrast, de-escalation strategies identified by the participants focused on reducing emotional distress. The approaches for dealing with continued high levels of agitation involved a number of "control and restraint" techniques as well as medication. Conclusion: The template allowed specialist multidisciplinary professionals to identify skills for the management of distress and agitated behaviour linked to the respective phase of arousal. The template has scope to guide practitioners to identify the detail needed for the management of behaviours that challenge. The findings have the potential to influence the contents of forthcoming guidelines on alternatives to psychotropics in dementia care.

OBJECTIVES: The effects of masupirdine on the neuropsychiatric symptoms were explored. METHODS: Masupirdine (SUVN-502) was evaluated for its effects on cognition in patients with moderate AD. The prespecified primary outcome showed no drug-placebo difference. Post hoc analyses of domains of the 12-item neuropsychiatric inventory scale were carried out. RESULTS: In a subgroup of patients (placebo, n = 57; masupirdine 50 mg, n = 53; masupirdine 100 mg, n = 48) with baseline agitation/aggression symptoms ≥1, a statistically significant reduction in agitation/aggression scores was observed in masupirdine 50 mg (95% confidence interval (CI), -1.9 to -0.5, p < 0.001) and masupirdine 100 mg (95% CI, -1.7 to -0.3, p = 0.007) treated arms at Week 13 in comparison to placebo and the effect was sustained for trial duration of 26 weeks in the masupirdine 50 mg treatment arm (95% CI, -2.3 to -0.8, p < 0.001). Similar observations were noted in the subgroup of patients (placebo, n = 29; masupirdine 50 mg, n = 30; masupirdine 100 mg, n = 21) with baseline agitation/aggression symptoms ≥3. In the subgroup of patients (placebo, n = 28; masupirdine 50 mg, n = 28; masupirdine 100 mg, n = 28) who had baseline psychosis symptoms and/or symptom emergence, a significant reduction in psychosis scores was observed in the masupirdine 50 mg (Week 4: 95% CI, -2.8 to -1.4, p < 0.001; Week 13: 95% CI, -3.3 to -1.3, p < 0.001) and masupirdine 100 mg (Week 4: 95% CI, -1.4 to 0, p = 0.046; Week 13: 95% CI, -1.9 to 0.1, p = 0.073) treatment arms in comparison to placebo. CONCLUSION: Further research is warranted to explore the potential beneficial effects of masupirdine on NPS.

BACKGROUND: The links between cerebral small vessel disease (CSVD) burden and neuropsychiatric symptoms (NPS) have not been fully studied. OBJECTIVE: We aimed to explore the associations of the CSVD burden with Neuropsychiatric Inventory (NPI) total scores and its subsyndromes in the elderly without dementia. METHODS: We investigated 630 non-demented participants from the Alzheimer's Disease Neuroimaging Initiative. All of them had NPI assessments and 3 Tesla MRI scans at baseline and 616 had longitudinal NPI assessments during the follow-up. Linear mixed-effects models were used to investigate the cross-sectional and longitudinal associations of CSVD burden with NPI total scores and its subsyndromes. RESULTS: Higher CSVD burden longitudinally predicted more serious neuropsychiatric symptoms, including NPS (pâ<â0.0001), hyperactivity (pâ=â0.0006), affective symptoms (pâ=â0.0091), and apathy (pâ<â0.0001) in the total participants. Lacunar infarcts (LIs), white matter hyperactivities (WMHs), and cerebral microbleeds (CMBs) might play important roles in the occurrence of NPS, since they were longitudinally associated with specific neuropsychiatric subsyndromes. LIs contributed to hyperactivity (pâ=â0.0092), psychosis (pâ=â0.0402), affective symptoms (pâ=â0.0156), and apathy (pâ<â0.0001). WMHs were associated with hyperactivity (pâ=â0.0377) and apathy (pâ=â0.0343). However, CMBs were only related to apathy (pâ=â0.0141). CONCLUSION: CSVD burden was associated with multiple neuropsychiatric symptoms, suggesting the importance of monitoring and controlling vascular risk factors. Different markers of CSVD were associated with specific subsyndromes of NPS, suggesting that different markers tended to occur in different encephalic regions.

BACKGROUND: Agitation and aggression are common in patients with Alzheimer's disease and related dementias and pose a significant burden on patients, caregivers, and the healthcare systems. Guidelines recommend personalized behavioral interventions as the first-line treatment; however, these interventions are often underutilized. The Standardizing Care for Neuropsychiatric Symptoms and Quality of Life in Dementia (StaN) study (ClinicalTrials.gov Identifier # NCT0367220) is a multisite randomized controlled trial comparing an Integrated Care Pathway, that includes a sequential pharmacological algorithm and structured behavioral interventions, with treatment-as-usual to treat agitation in dementia in long-term care and inpatient settings. OBJECTIVE: To describe the rationale and design of structured behavioral interventions in the StaN study. METHODS: Structured behavioral interventions are designed and implemented based on the following considerations: 1) personalization, 2) evidence base, 3) dose and duration, 4) measurement-based care, and 5) environmental factors and feasibility. RESULTS: The process to design behavioral interventions for each individual starts with a comprehensive assessment, followed by personalized, evidence-based interventions delivered in a standardized manner with ongoing monitoring of global clinical status. Measurement-based care is used to tailor the interventions and integrate them with pharmacotherapy. CONCLUSION: Individualized behavioral interventions in patients with dementia may be challenging to design and implement. Here we describe a process to design and implement individualized and structured behavioral interventions in the context of a multisite trial in long-term care and inpatient settings. This process can inform the design of behavioral interventions in future trials and in clinical settings for the treatment of agitation in dementia.

BACKGROUND: A case series suggested efficacy for lithium to treat agitation in dementia, but no placebo-controlled trials have been conducted. OBJECTIVES: To evaluate low-dose lithium treatment of agitation in Alzheimer's disease (AD). METHOD: In a four-site trial, patients with AD and agitation/aggression score ≥4 on the Neuropsychiatric Inventory (NPI) were randomized, double-blind, to lithium carbonate 150-600 mg daily or placebo for 12 weeks. Primary efficacy outcome was change in NPI agitation/aggression; secondary efficacy outcome was treatment response (30% reduction in NPI score for agitation/aggression plus psychosis and a Clinical Global Impression (CGI) score of much or very much improved). Safety profile of lithium was assessed. RESULTS: Fifty-eight of 77 patients (75.3%) completed the trial. In linear mixed effects model analyses, lithium was not significantly superior to placebo for agitation/aggression. Proportion of responders was 31.6% on lithium and 17.9% on placebo (χ2=1.26, pâ¯=â¯0.26). Moderate or marked improvement (CGI) was greater on lithium (10/38=36.8%) than placebo (0/39=0%, Fisher's exact test p <0.001). In exploratory analyses, improvement on lithium was greater than placebo on NPI delusions and irritability/lability (p's<0.05). Lithium showed greater reduction than placebo in patients with high Young Mania Rating Scale scores (ß=5.06; 95%CI,1.18 to 8.94, pâ¯=â¯0.01). Oral dose and serum levels demonstrated similar associations with efficacy outcomes. Lithium did not differ significantly from placebo on safety outcomes. CONCLUSIONS: Low-dose lithium was not efficacious in treating agitation but was associated with global clinical improvement and excellent safety. A larger trial may be warranted of likely lithium-responsive behavioral symptoms that overlap with mania.

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) have a large impact on the quality of life of patients with Alzheimer's disease (AD). Few studies have compared BPSD between early-onset (EOAD) and late-onset (LOAD) patients, finding conflicting results. OBJECTIVE: The aims of this study were to: 1) characterize the presence, overall prevalence, and time of occurrence of BPSD in EOAD versus LOAD; 2) estimate the prevalence over time and severity of each BPSD in EOAD versus LOAD in three stages: pre-T0 (before the onset of the disease), T0 (from onset to 5 years), and T1 (from 5 years onwards); 3) track the manifestation of BPSD sub-syndromes (i.e., hyperactivity, psychosis, affective, and apathy) in EOAD versus LOAD at T0 and T1. METHODS: The sample includes 1,538 LOAD and 387 EOAD diagnosed from 1996 to 2018. Comprehensive assessment batteries, including the Neuropsychiatric Inventory (NPI), were administered at the first medical assessment and at different follow-up period. RESULTS: The overall prevalence for the most of BPSD was significantly higher in EOAD compared to LOAD whereas most BPSD appeared significantly later in EOAD patients. Between the two groups, from pre-T0 to T1 we recorded a different pattern of BPSD prevalence over time as well as for BPSD sub-syndromes at T0 and T1. Results on severity of BPSD did not show significant differences. CONCLUSION: EOAD and LOAD represent two different forms of a single entity not only from a neuropathological, cognitive, and functional level but also from a psychiatric point of view.

BACKGROUND AND PURPOSE: The Cohen-Mansfield Agitation Inventory (CMAI) is a widely used measure of agitation. The purpose of this study was to test the internal consistency, reliability, and validity of short-form CMAI in a sample of nursing home residents with cognitive impairment and examine if it is invariant across gender. METHODS: This study utilized baseline data from a randomized trial including 553 residents from 55 nursing homes. Data was analyzed using structural equation modeling. RESULTS: Confirmatory factory analysis supported the three-factor structure including aggressive (α = .794), physically nonaggressive (α = .617), and verbally agitated (α = .718) behaviors. Invariance testing confirmed that the shortened measure is invariant across gender. CONCLUSIONS: Findings provide validity evidence of short-form CMAI to assess agitation and gender differences in agitation in nursing home population.

BACKGROUND: Neuropsychiatric symptoms (NPS) such as aggression, apathy, agitation, and wandering may occur in up to 90%of dementia cases. International guidelines have suggested that non-pharmacological interventions are as effective as pharmacological treatments, however without the side effects and risks of medications. An occupational therapy method, called Tailored Activity Program (TAP), was developed with the objective to treat NPS in the elderly with dementia and has been shown to be effective. OBJECTIVE: Evaluate the efficacy of the TAP method (outpatient version) in the treatment of NPS in individuals with dementia and in the burden reduction of their caregivers. METHODS: This is a randomized, double-blind, controlled clinical trial for the treatment of NPS in dementia. Outcome measures consisted of assessing the NPS of individuals with dementia, through the Neuropsychiatric Inventory-Clinician rating scale (NPI-C), and assessing the burden on their caregivers, using the Zarit Scale. All the participants were evaluated pre-and post-intervention. RESULTS: 54 individuals with dementia and caregivers were allocated to the experimental (nâ=â28) and control (nâ=â26) groups. There was improvement of the following NPS in the experimental group: delusions, agitation, aggressiveness, depression, anxiety, euphoria, apathy, disinhibition, irritability, motor disturbance, and aberrant vocalization. No improvement was observed in hallucinations, sleep disturbances, and appetite disorders. The TAP method for outpatient settings was also clinically effective in reducing burden between caregivers of the experimental group. CONCLUSION: The use of personalized prescribed activities, coupled with the caregiver training, may be a clinically effective approach to reduce NPS and caregiver burden of individuals with dementia.

INTRODUCTION: The 2017 European Union-North American Clinical Trials in Alzheimer's Disease Task Force recommended development of clinician-rated primary outcome measures for Alzheimer's disease (AD) agitation trials, incorporating International Psychogeriatric Association (IPA) criteria. METHODS: In a modified Delphi process, Cohen-Mansfield Agitation Inventory (CMAI) and Neuropsychiatric Inventory-Clinician (NPI-C) items were mapped to IPA agitation domains generating novel instruments, CMAI-IPA and NPI-C-IPA. Validation in the Agitation and Aggression AD Cohort (A3C) assessed minimal clinically important differences (MCIDs), change sensitivity, and predictive validity. RESULTS: MCID was -17 (odds ratio [OR] = 14.9, 95% confidence interval [CI] = 6.8-32.6) for CMAI; -5 (OR = 9.3, 95% CI = 4.0-21.2) for CMAI-IPA; -3 (OR = 11.9, 95% CI = 4.1-34.8) for NPI-C-A+A; and -5 (OR = 7.8, 95% CI = 3.4-17.9) for NPI-C-IPA at 3 months. Areas under the curve suggested no scale better predicted global clinician ratings. Sensitivity to change for all measures was high. CONCLUSION: Internal consistency and reliability analyses demonstrated better accuracy for the NPI-C-IPA than for the CMAI-IPA and can be used for agitation clinical trial inclusion, and for response to intervention.

BACKGROUND: To present methodology, baseline results and longitudinal course of the Agitation and Aggression in patients with Alzheimer's Disease Cohort (A3C) study. OBJECTIVES: The central objective of A3C was to study the course, over 12 months of clinically significant Agitation and Aggression symptoms based on validated measures, and to assess relationships between symptoms and clinical significance based on global ratings. DESIGN: A3C is a longitudinal, prospective, multicenter observational cohort study performed at eight memory clinics in France, and their associated long-term care facilities. SETTING: Clinical visits were scheduled at baseline, monthly during the first 3 months, at 6 months, at 9 months and at 12 months. The first three months intended to simulate a classic randomized control trial 12-week treatment design. PARTICIPANTS: Alzheimer's Disease patients with clinically significant Agitation and Aggression symptoms lived at home or in long-term care facilities. MEASUREMENTS: Clinically significant Agitation and Aggression symptoms were rated on Neuropsychiatric Inventory (NPI), NPI-Clinician rating (NPI-C) Agitation and Aggression domains, and Cohen Mansfield Agitation Inventory. Global rating of agitation over time was based on the modified Alzheimer's Disease Cooperative Study-Clinical Global Impression of Change. International Psychogeriatric Association "Provisional Diagnostic Criteria for Agitation", socio-demographics, non-pharmacological approaches, psychotropic medication use, resource utilization, quality of life, cognitive and physical status were assessed. RESULTS: A3C enrolled 262 AD patients with a mean age of 82.4 years (SD ±7.2 years), 58.4% women, 69.9% at home. At baseline, mean MMSE score was 10.0 (SD±8.0), Cohen Mansfield Agitation Inventory score was 62.0 (SD±15.8) and NPI-C Agitation and Aggression clinician severity score was 15.8 (SD±10.8). According to the International Psychogeriatric Association agitation definition, more than 70% of participants showed excessive motor activity (n=199, 76.3%) and/or a verbal aggression (n=199, 76.3%) while 115 (44.1%) displayed physical aggression. The change of the CMAI score and the NPI-C Agitation and Aggression at 1-year follow-up period was respectively -11.36 (Standard Error (SE)=1.32; p<0.001) and -6.72 (SE=0.77; p<0.001). CONCLUSION: Little is known about the longitudinal course of clinically significant agitation symptoms in Alzheimer's Disease about the variability in different outcome measures over time, or the definition of a clinically meaningful improvement. A3C may provide useful data to optimize future clinical trials and guide treatment development for Agitation and Aggression in Alzheimer's Disease.

BACKGROUND: Previous studies have suggested that screen time (ST) has a negative effect on children's emotional and behavioral health, but there are few longitudinal studies that have been conducted with infants and toddlers. This study sought to examine the effect of ST in early childhood on emotional and behavioral problems in children aged 4 years, based on a birth cohort study in China. METHODS: A total of 2492 children aged 4 years were enrolled in this study. The parents and guardians of each child completed a questionnaire that included items eliciting information on children's birth information, socio-demographic information at baseline, and ST at each follow-up. Emotional and behavioral problems were assessed using the Strengths and Difficulties Questionnaire (SDQ) at 4 years of age. Multivariate logistic analysis was used to explore the effects of ST on emotional and behavioral problems. RESULTS: The percentages of children with ST > 0 h/day at age 0.5 years, ST > 2 h/day at age 2.5 years, and ST > 2 h/day at age 4 years were 45.7, 55.5, and 34.5% respectively. The prevalence of emotional and behavioral problems was 10.8%. ST at 6 months was a risk factor for emotional symptoms and hyperactivity at the age of 4 years. ST at age 2.5 years was a risk factor for hyperactivity at the age of 4 years. However, ST at age 4 years was a risk factor for total difficulties, conduct problems, peer problems, hyperactivity, and prosocial behavior. CONCLUSIONS: Higher ST exposure at early childhood is associated with later emotional and behavioral problems. In particular, sustained high ST exposure is a risk factor for behavioral problems. These findings suggested the importance of controlling ST to prevent the occurrence of emotional and behavioral problems in the early years.

This research investigated whether delayed school entry was associated with higher achievement in national tests of reading and numeracy in Grades 3, 5, 7, and 9 (n = 2,823). Delayed entry was related to advantages in reading (0.14 SD) and numeracy (0.08 SD) at Grade 3, although little variance was explained (1%-2%). This slight advantage persisted for both domains in Grades 5 and 7, albeit with smaller effects. In Grade 9 there was no association between delayed entry and either reading or numeracy. Exploratory analyses with subsamples in each grade (n = 424-667) revealed no associations between delayed entry and achievement after controlling for inattention and hyperactivity, and negative associations between inattention and achievement in all grades in both domains (-0.33, -0.49 SD).

OBJECTIVES: Nursing home residents with dementia are sensitive to detrimental auditory environments. This paper presents the first literature review of empirical research investigating (1) the (perceived) intensity and sources of sounds in nursing homes, and (2) the influence of sounds on health of residents with dementia and staff. DESIGN: A systematic review was conducted in PubMed, Web of Science and Scopus. Study quality was assessed with the Mixed Methods Appraisal Tool. We used a narrative approach to present the results. RESULTS: We included 35 studies. Nine studies investigated sound intensity and reported high noise intensity with an average of 55-68 dB(A) (during daytime). In four studies about sound sources, human voices and electronic devices were the most dominant sources. Five cross-sectional studies focused on music interventions and reported positives effects on agitated behaviors. Four randomized controlled trials tested noise reduction as part of an intervention. In two studies, high-intensity sounds were associated with decreased nighttime sleep and increased agitation. The third study found an association between music and less agitation compared to other stimuli. The fourth study did not find an effect of noise on agitation. Two studies reported that a noisy environment had negative effects on staff. CONCLUSIONS: The need for appropriate auditory environments that are responsive to residents' cognitive abilities and functioning is not yet recognized widely. Future research needs to place greater emphasis on intervention-based and longitudinal study design.

Agitation is a common, treatable symptom that profoundly impacts quality of life and exacerbates caregiver fatigue in the hospice setting for patients with dementia. The objective of this study was to analyze the efficacy of tailored nonpharmacological interventions for mitigation of unwanted behaviors in the population of patients with behavioral and psychological symptoms in dementia while receiving hospice care. The 4-domain Pittsburgh Agitation Scale (PAS; Motor, Verbal, Aggressive, Resistance to Care) was used for multiple baseline and posttest measurements of agitation. Effectiveness of nonpharmacological interventions was evaluated using analysis of variance for repeated measures for the total PAS score. Motor agitation was the presenting problem with highest-rated severity compared with Verbal, Aggression, and Resistance to Care domains. Analysis of variance demonstrated no difference between baseline referral and pretest total PAS measures (P = .8), but a significant drop in total PAS agitation after intervention (P < .001). The best outcomes, however, were with patients receiving both nonpharmacological and standard pharmacological interventions as opposed to nonpharmacological interventions alone (P = .034). For patients with dementia presenting with behavioral and psychological symptoms, selected nonpharmacological interventions provide significant mitigation of agitation.
